I am an active user of Kucoin Exchange. I love the GUI and App too. In addition the team works a lot for promotions and twitter bounties. They are very active in Social Media and personally I’ve experienced a very good support team. In this exchange you can find NEO, ETH, BTC, KCS and USTD markets. The volume is not comparable tot he hugest Exchange but It’s very close tot hem. It’s Cortex allows users to write machine-learning programs on the blockchain and submit interactions that are dependent upon other contracts.
